The action of changing mixed cement from a fluid state to a solid state is called setting of cement and time required for it to set is called setting time of cement. Setting time is affected by a few factors including composition of cement, amount of gypsum in cement, fineness of cement, water cement ratio, type of admixture used, storage of cement and is generally tested by Vicat apparatus. In this section, you will find the Vicat test set, Automatic vicat apparatus, Computer-controlled Vicat needle apparatus for testing the setting time of cement. |
